[0002] Forging production is a very old industry, but the mass production and application of aluminum alloy forgings began in the 1950s. After decades of modernization, it has achieved rapid development in industrial equipment, mold design and manufacturing, production processes and technologies, as well as product varieties and specifications, production scale and quality.
[0003] A large number of new forging processes and technologies have been developed in the field of aluminum and aluminum alloy forging technology, such as liquid die forging, semi-solid die forging, isothermal forging, powder forging, multi-directional forging, non-slope precision die forging, partial die forging, and canned die forging. Aluminum and aluminum alloy forging technology has played a significant role in simplifying processes, reducing procedures, saving energy, expanding quality, increasing specifications, improving quality and production efficiency, protecting the environment, reducing labor intensity, and improving economic benefits. Specialized computer software is then used to provide reliable guarantees for controlling key process parameters such as forging temperature, forging pressure, degree of deformation (understressing), and process lubrication, as well as controlling product size, internal structure, and mechanical properties.
[0004] However, in the process of forging aluminum and aluminum alloys, it is not possible to demold each part of the product at the same time during product forming, which will cause defects in the edges and corners of the product. In addition, there is no mold in the existing technology that can perform two processes simultaneously when forging aluminum alloy lower control arms, so the forging production efficiency cannot be improved. Therefore, it is urgently needed to design an integrated mold for forging aluminum alloy lower control arms with a transfer mechanism to solve the above problems. Utility Model Content

There are multiple first guide rods, which are arranged in parallel, and their tops are connected to the first connecting plate and their bottoms are connected to the first adapter frame. There are two first ejector frames, and the two first ejector frames are symmetrically arranged at both ends of the first adapter frame. The lower parts of the two first ejector frames are N-shaped, and the vertical frames on both sides of the N-shaped lower part extend or retract through the outer sides of the pre-forging die cavity and the final forging die cavity of the lower mold.
[0009] Furthermore, the first final forging transfer mechanism and the second final forging transfer mechanism each include a second connecting plate, a second guide rod, a second transfer frame and a second ejector frame. There are a plurality of second guide rods, which are arranged in parallel, and their tops are connected to the second connecting plate and their bottoms are connected to the second transfer frame.

The lower parts of the two second ejector frames are n-shaped, and the vertical frames on both sides of the n-shaped lower part extend or retract through the outer sides of the pre-forging die cavity and the final forging die cavity of the upper mold.
[0010] Furthermore, a first stopper is provided at one end of the upper mold and a groove is provided at the other end, and a slope is provided at the bottom of the first stopper.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.
[0024] The following is a specific embodiment of the present invention and the attached Figure 1-5 To explain in detail, specifically discloses an integrated die for forging an aluminum alloy lower control arm with a transfer mechanism, comprising an upper die 1, a lower die 2, a first pre-forging transfer mechanism 3, a first final forging transfer mechanism 4, a second pre-forging transfer mechanism 5 and a second final forging transfer mechanism 6. A pre-forging die cavity 11 and a final forging die cavity 12 are provided on opposite surfaces of the upper die 1 and the lower die 2. The pre-forging die cavity 11 and the final forging die cavity 12 are both Y-shaped. When forging the aluminum alloy lower control arm, the aluminum alloy lower control arm under two processes can be forged at the same time, thereby improving the forging production efficiency. The enclosing arrangement of the pre-forging die cavity 11 and the final forging die cavity 12 enables the intersection of the two enclosed parts to be demolded by using the same transfer mechanism, thereby reducing the area occupied by the die cavity and also reducing the problem of waste in manufacturing cost of the transfer mechanism.
[0025] The lower parts of the first pre-forging adapter mechanism 3 and the first final forging adapter mechanism 4 both pass through the upper die 1 and extend out, and their lower ends are located outside the pre-forging die cavity 11 and the final forging die cavity 12 of the upper die 1; the upper parts of the second pre-forging adapter mechanism 5 and the second final forging adapter mechanism 6 both pass through the lower die 2 and extend out, and their upper ends are located outside the pre-forging die cavity 11 and the final forging die cavity 12 of the lower die 2.
[0026] The second pre-forging adapter mechanism 5 and the first pre-forging adapter mechanism 3 are driven to reciprocate relative to each other through the lower press and the upper press respectively, and the second final forging adapter mechanism 6 and the first final forging adapter mechanism 4 are driven to reciprocate relative to each other through the lower press and the upper press respectively.
[0027] The first pre-forging adapter mechanism 5, the first final forging adapter mechanism 4, the second pre-forging adapter mechanism 5 and the second final forging adapter mechanism 6 pass through the upper die 1 and the lower die 2 respectively. When the products in the pre-forging die cavity 11 and the final forging die cavity 12 need to be demolded, the upper press and the lower press respectively drive the first pre-forging adapter mechanism 5 and the first final forging adapter mechanism 4 and the second pre-forging adapter mechanism 5 and the second final forging adapter mechanism 6 to approach each other, and simultaneously suppress the products to rise or fall, so as to drive the aluminum alloy lower control arm blank and the final formed aluminum alloy lower control arm to be demolded, which effectively improves the forging efficiency and can solve the problem in the prior art that there is no mold that can forge the blank and the formed product of the aluminum alloy lower control arm at the same time.
[0028] The first pre-forging transfer mechanism 3 and the second pre-forging transfer mechanism 5 both include a first connecting plate 31, a first guide rod 32, a first transfer frame 33 and a first ejector frame 34. There are multiple first guide rods 32, which are arranged in parallel, and their tops are connected to the first connecting plate 31, and their bottoms are connected to the first transfer frame 33. There are two first ejector frames 34, and the two first ejector frames 34 are symmetrically arranged at both ends of the first transfer frame 33. The lower parts of the two first ejector frames 34 are n-shaped, and the vertical frames on both sides of the lower part of the n-shaped portion extend or retract through the outer sides of the pre-forging die cavity 11 and the final forging die cavity 12 of the lower mold 2.
[0029] The first final forging transfer mechanism 4 and the second final forging transfer mechanism 6 both include a second connecting plate 41, a second guide rod 42, a second transfer frame 43 and a second ejector frame 44. There are multiple second guide rods 42, which are arranged in parallel, and their tops are connected to the second connecting plate 41, and their bottoms are connected to the second transfer frame 43. There are two second ejector frames 44, and the two second ejector frames 44 are arranged in parallel on one side of the second transfer frame 43. The lower parts of the two second ejector frames 44 are n-shaped, and the vertical frames on both sides of the lower part of the n-shaped pass through the outer sides of the pre-forging die cavity 11 and the final forging die cavity 12 of the upper mold 1 to extend or retract.
[0030] A first stopper 14 is provided at one end of the upper mold 1, and a groove 15 is provided at the other end. A slope 141 is provided at the bottom of the first stopper 14. A second stopper 21 is provided at one end of the lower mold 2, and the second stopper 21 cooperates with the groove 15. A bevel 22 cooperating with the bevel 141 of the first stopper 14 is provided at the other end of the lower mold 2. The cooperating design of the bevel 141 of the first stopper 14 of the upper mold 1 and the bevel 22 of the lower mold 2, as well as the design of the groove 15 of the upper mold 1 and the second stopper 21, can effectively control the thickness of the aluminum alloy lower control arm, thereby improving the dimensional accuracy of the aluminum alloy lower control arm and improving product quality.
[0031] The workflow of this utility model:
[0032] The cast rod is placed between the pre-forging die cavity 11 of the upper die 1 and the lower die 2, the upper press pushes the upper die 1 downward, and the lower press pushes the lower die 2 upward, thereby pressing the cast rod to preform the cast rod. After the preforming is completed, the upper die 1 is opened upward. At the same time, the first pre-forging adapter mechanism 3 and the second pre-forging adapter mechanism 5 are relatively close to each other under the drive of the upper press and the lower press, so as to drive the n-shaped frame at the lower part of the first ejection frame 34 of the first pre-forging adapter mechanism 3 and the n-shaped frame at the upper part of the first ejection frame 34 of the second pre-forging adapter mechanism 5 to simultaneously drive the preformed aluminum alloy lower control arm blank to separate from the pre-forging die cavity 11 of the lower die 2, so as to facilitate demolding of the aluminum alloy lower control arm blank;
[0033] When the upper mold 1 and the lower mold 2 are fully opened, the aluminum alloy lower control arm blank on the pre-forging die cavity 11 of the lower mold 2 is moved to the final forging die cavity 12 of the lower mold 2, and the outline of the aluminum alloy lower control arm blank is aligned with the outline on the final forging die cavity 12, and then the upper mold 1 and the lower mold 2 are closed to finally form the aluminum alloy lower control arm blank. After forming, the upper mold 1 is opened upward, and at the same time, the first final forging adapter mechanism 4 and the second final forging adapter mechanism 6 are relatively close to each other under the drive of the upper press and the lower press, so as to drive the n-shaped frame at the lower part of the second ejector frame 44 of the first final forging adapter mechanism 4 and the n-shaped frame at the upper part of the first ejector frame 34 of the second final forging adapter mechanism 6 to simultaneously drive the periphery of the aluminum alloy lower control arm product to reciprocate upward or downward at the same time, so as to drive the aluminum alloy lower control arm product out of the final forging die cavity 12 of the lower mold 2, so as to facilitate the demoulding of the aluminum alloy lower control arm blank and improve the quality of the product;
[0034] And the corresponding cast rods and product blanks can be placed in the subsequent pre-forging die cavity 11 and the final forging die cavity 12, so that the two processes can be forged together, and at the same time, the first ejector frame 34 at the junction of the pre-forging die cavity 11 and the final forging die cavity 12 can simultaneously demold the blank products and formed products in the pre-forging die cavity 11 and the final forging die cavity 12, so as to effectively improve the forging efficiency, and reduce the manufacturing cost of the switching mechanism, and at the same time solve the problem in the prior art that there is no mold that can forge the two production states of the blank and the formed product of the aluminum alloy lower control arm at the same time.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
